Wow. Unless I missed something, his postings are all on the exchange except for a single tech support post. Quite a contributor to the blade forums community.
Yup. Only here to buy and sell.
I had a couple dealings with LIN that worked out fine, but it is rather shady how he tries to purchase things without full disclosure of his situation. I caught on to it because the fee pp charged me for his transaction (cross border transaction fee is an extra 1%) was slightly higher than normal, but it's such a small amount that it could easily slip by unnoticed. I'd say that if his repackagers didn't package it properly, that is not your problem and needs to be brought to paypals attention.

Interesting. People need to be up front in all their dealings. Communication is key. If you are using a proxy it should be disclosed.
